My requirement is simple

I have a new image in my Slot0:XXXX.bin

1. which is the command to change the boot sequence to slot0?

2. Do I need to change anything in config-register?

Hi Ganesh,

Boot process involves two software images: ROM monitor and supervisor engine system code. When the switch is powered up or reset, the ROM-monitor code is executed. Depending on the nonvolatile RAM (NVRAM) configuration, the switch either stays in ROM-monitor mode or loads the supervisor engine system code.

Check  out the below link hope this will clear your query !!
